[Xen-devel] Re: HVM boot of Windows domU using VHD fails (Xen 4.1-unstable CS 21787, dom0 kernel 2.6.32.16)

[Dante Cinco <dantecinco@xxxxxxxxx>]

I found the following in daemon.log and it might shed some light on the problem:

When I went back to Xen 4.0.0 final and dom0 kernel 2.6.32.14 and
successfully booted up the Windows domU, the following showed up in
daemon.log:

And when I shutdown the Windows domU:
